OPERATING MECHANISM FOR PHONOGRAPHS.

Application filed Kay 28, 1911.

.To all whom it may concern:

'lyn, Kings county, in the State of New York, have invented certain new and useful Improvements in Operating Mechan sm for Phono raphs, of which the following is a full, ear, and exact specification.

My invention relates to improvements in operating mechanism for phonographs and other apparatus and the same has for its object more particularly to provide a. simple, eiiicient and reliable drivmg mechanism comprising two se arate power units which are adapted to be rought into operation at will, to actuate the disk shaft of the phonograph.

Further, said invention has for its ob ect to provide a motive power for phonographs comprising a spring or primary motor, and an electric or secondary motor, either of which may be brou ht into operation at will to rotate the she of the spring motor.

Further, said invention has for its object to provide a driving mechanism comprising a spring motor, and an electric motor, an intermediate mechanism whereby one or the other of said motor units may be brought into or out of engagement, at will, with the shaft of the spring motor, and means for locking said intermediate mechanism to its adjusted position.

To the attainment of the aforesaid objects and ends, my invention consists in the novel details of construction and in the combination, connection and arrangement of parts hereinafter more fully described and then pointed out in the claims.

In the accompanying drawings, forming part of this specification, wherein like numerals of reference indicate like parts, Figure 1 is a side view partly in section taken on the line 1-1 of Fig. 2, showing a phonograph with operating mechanism constructed according to, and embodying my said invention: Fig. 2 is a horizontal section taken on the line 2-2 of Fig. 1, and Fig. 3 is a detail section taken on the line 3-3 of Fig. 2 looking in the direction of the arrow,

In said drawings designates a phonograph of the usual construction comprising a. casing 11 having a bin ed top or cover 12 above which is revolu 1y supported a plate 18 adapted to receive the record disk Specification of Letters Patent.

Patented July 11, 1916.

Serial No. 628,927.

14. The plate 13 is supported upon a vertical shaft 15 mounted in suitable bearings, and having a worm gear 16 adjacent to its lower end meshing with a gear wheel 17 connected to the barrel 18 inclosing the drivin spring 19.

2O enotes a shaft supported in bearings 21, 21 arranged upon a frame 21 dependin from the under side of the cover 12. Said shaft extends horizontally through the spring barrel 18 and is connected intermediate its ends to the inner end of the coil spring 19 arranged within said barral 18. Upon the shaft 20, adjacent to one end thereof, is fixed a gear wheel 22 in mesh with a gear wheel 23 which latter in turn meshes with a gear wheel 24 fixed upon a winding stem 25 which has its outer end terminating adjacent to an aperture (not seen) in the side of the casing 11. The end of said stem 25 is adapted to receive a key whereby said spring of the motor may be wound up. The opposite end of said shaft 20 is su ported within a socket 26 provided in a siaft 27 mounted in the bearing 21. At the outer end of said shaft 27 is fixed a spur gear 28, and at the inner end of the shaft 27 is provided a flanged head 29 which is secured to the gear wheel 17 on the barrel 18 by screws, or other suitable means. In the bottom of the casing 11 is secured an electric motor 31 having a shaft 32 extending therefrom which has its free end supported in a bearing 33. 34 denotes a worm gear arranged upon said shaft 32, and 35 denotes a driven shaft in bearings 36, 36 and arranged in an inclined position at right angles to the shaft 32 of the electric motor 31, and to the shaft sections 20, 27 of the spring motor 18. At one end of the shaft 35 is fixed a gear 37 meshing with the worm gear 34 on the shaft 32 of the electric motor. and at the opposite end of said shaft 35 is fixed a bevel gear 38 which meshes with a bevel gear 39 fixed u on a vertical shaft 40. The lower end 0 said shaft 40 is pivotally supported in a bear ing 41 secured upon the base of the casing 11, and the upper portion of said shaft 40 is disposed within a rectangular head 42 having pins 43 secured therein and projecting outward therefrom in opposite directions. longer than the other, and serves as a finger portion, is visible.

Only one of said pi'ns which is i 44 denotes a bracket secured upon the inner side of the casing 11 having its free end bifurcated and slotted to receive the head 42 on the shaft 40, and the ends of the pins 43 extending therefrom. The upper surface of the head 42 is provided with a plurality of recesses 45, 45, and 46 denotes a spring having one end secured upon the up er side of the bracket 44 by screw 47 anc its free end provided with a projection or tooth 48 adapted to en age the recesses 45, 45 in the upper side 0 the head 42.

49 denotes a knob or finger portion provided upon the upper surface of the spring 46 whereby the projection or tooth 48 upon the under side of the spring may be released from its engagement with the recesses 45, 45 arranged in the upper side of the head 42.

50 denotes a. worm gear fixed upon the pivotally supported shaft 40, and adapted to mesh with the spur gear 28 arranged upon the shaft section 27 of the motor.

Upon the outer side of the casing 11 is arranged a switch 51.

52, 52 denote conductors leading from the switch 51 to the electric motor 31, and 53, 53 denote conductors leading from a source of electric energy to the switch 51, and including a resistance 54.

The operation of the apparatus is as follows: When it is desired to operate the phonograph by means of the primary --or spring motor, it merely becomes necessary to disconnect the worm gear 50 from the spur gear 28 by releasing the projection on the under side of the spring 46 from its engagement with the recesses 45 in the upper side of the head 42, and then moving the upper end of the shaft 40 aside .until the teeth of the worm 50 are disengaged from the teeth of the spur gear 28. Thereupon the spring motor may be wound up and the same will operate the apparatus in the usual manner.

\Vhen it is desired to operate the a paratus by means of the electric or secondary motor 31, it merely becomes necessary to shift the worm gear 50 into engagement with the spur gear 28, as indicated at Fig. 1 of the drawings, and then operate the switch 51 to complete the electric circuit. In this arrangement power will be transmitted from the shaft 32 to the worm car 34, gear 37, shaft 35, bevel gears 38 an 39, shaft 40, worm 50, spur gear 28 to the shaft section 27 and thence to the gear 17 on the spring barrel, thereby causing rotation of the vertical shaft 15 by means of the worm 16. The speed with which the electric motor operates may be controlled by the resistance 54.

It will be observed that by means of my invention I am enabled to provide a supplemental driving mechanism which is adapted to actuate the main shaft of the spring motor, independently of the spring. This supplemental driving mechanism being particularly useful where large record disks are used and which are rotated at a uniform rate of speed from beginning to end.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is
